Catch SportsDay On Air twice per week on Fox Sports Southwest, when Dallas Morning News experts discuss hot sports topics from the Cowboys, Mavericks, Stars, Rangers and colleges (check our TV listings for air times). Here are a few highlights from Thursday's episode featuring Evan Grant and Kevin Sherrington:

On the Mavs signing Derek Fisher:

Grant: “I just don’t see where the Mavs are right now with Dirk not back and with this team struggling, and they’re fighting for maybe a seventh or eighth seed. What is bringing in a 38-year-old point guard going to do? What is it going to help? Will he help in the locker room? Probably, but I think that you’ve got to learn what these young guys have whether they’re part of your future or not.”

Sherrington: “This is just a patch work. They’re going through a huge rollercoaster. They started off so great and who would have thought that. I wrote a column talking about what a great job (Darren) Collison was doing and then the guy goes in the tank after that. The point is this year is not about next year. This year is about nothing. They brought in all these guys because they want to make sure they can clear all that cap space so hopefully they can finally draw in that great free agent star.”
